Lots of psychology studies fail to produce the same results when they are repeated. Does that mean we shouldn't trust science?
Most antibiotics can't tell the difference between good and bad bacteria. That means medicines can kill helpful bacteria in your gut while they're obliterating the ones making you sick.
A refrigerator-sized machine could someday make lifesaving drugs on site when outbreaks occur or where medicine is in short supply, like on the battlefield.
